Abstract:
Memories, systems, and methods for forming memory cells are disclosed. One such memory cell includes a charge storage node that includes nanodots over a tunnel dielectric and a protective film over the nanodots. In another memory cell, the charge storage node includes nanodots that include a ruthenium alloy. Memory cells can include an inter gate dielectric over the protective film or ruthenium alloy nanodots and a control gate over the inter gate dielectric. The protective film and ruthenium alloy can be configured to protect at least some of the nanodots from vaporizing during formation of the inter gate dielectric.
Abstract:
A method of forming a gate dielectric comprising silicon and oxygen is provided. The gate dielectric may also include nitrogen or another high k material. In one aspect, forming the gate dielectric includes annealing a substrate in an oxidizing atmosphere to form a silicon oxide layer, depositing a silicon nitride layer or a high k layer on the silicon oxide layer by a vapor deposition, oxidizing an upper surface of the silicon nitride layer or high k layer, and then annealing the substrate. The gate dielectric may be formed within an integrated processing system.

A gate insulating film 3 is formed of an insulative inorganic material containing silicon and oxygen as a main material. The gate insulating film 3 contains hydrogen atoms. A part of the absorbance of infrared radiation of which wave number is in the range of 830 to 900 cm is less than both the absorbance of infrared radiation at the wave number of 830 cm and the absorbance of infrared radiation at the wave number of 900 cm when the insulating film to which an electric field has never been applied is measured by means of Fourier Transform Infrared Spectroscopy at room temperature.

Abstract:
A method is provided for forming a metal-silicon-containing film on a substrate by pulsed chemical vapor deposition. The method includes providing the substrate in a process chamber, maintaining the substrate at a temperature suited for chemical vapor deposition of a metal-silicon-containing film by thermal decomposition of a metal-containing gas and a silicon-containing gas on the substrate, exposing the substrate to a continuous flow of the metal-containing gas, and during the continuous flow, exposing the substrate to sequential pulses of the silicon-containing gas.
